.To all whom it may concern:

Be it known that l, CYsILLn Corns, citizen of France. residing at Lyon-Monplaisir, France, have invented new and useful linprorements in or Relating to (louplings for Shafts and the Like, of which the following is a specification.

This invention relates to a coupling which forms a universal joint between a driving l'ly wheel and the clutch cup of clutch, by means of which permanentce tering of the clutch cup is obtained in spite of oscillations in any direction, the constant drying being obtained by means of two special tenons held in the driving fly wheel and engaging or sliding in corresponding grooves made in the clutch cu This method of connection ismore particularly applicable to motor vehicles in combination with the. en of'a clutch of any desired type.

lhe accompanying drawing illustrates a -constr uction of the coupling between the -tly wheel of an engine and a clutch with multiple disks;

Fi re 1 is a longitudinal section on the line O l) of Fig. Fig. 2 is a cross-sec tion on the line A B of Fig. 1. Figs. 3, e and 5 are details of a-driying tenon. (3 is a modified construction showing the connection applied to a fly wheel with a cylin. drical recess.

According to this invention. the driving fly wheel 1 secured to the ma shaft rotates or drives the Lup' 3 of a clutch which in this case is of the type with mut All type.

The cup 3 engages with the (.lll wheel so as to engage with the int the rim of the fly wheel by means of circumference which has the sectional of an are or portion of a sphere of are. R. The rim of the fly wheel is recessed a the interior, so as to have a sectional for-moi. similar c-Lirvature or of the same radius ll. the common center 0 ofthcse' spherical portions being situated at a point in the extension of the axis of the main shaft '2. For facilitating the en agement of the cup with the. fly wheel, a chambered portion l may be provided on the edge where the engage ment with the rim' takes place- The driving of the cup 3 by the fly wheel 1 is obtained by means of two tenons 5 of cylindrical shape mounted to fit exactly in holes 6 drilled radially in the thickness of l'lll ill-5 (fi l the of the fly wheel. Each tenon is continued by a flattened portion '7 for engaging with or fitting into a. suitable recess 8 cut longitudinally in the spherical ed e of the clutch cup. The tenons 5 are hel in position in their recesses by means of a screw plug '9 secured by a pin 10. Owing to this arrangement of the tcnons '5, the clutch cup can oscillate about the center 0 of the can tering sphere, and its axis can be inclined upward or downward. to the right or to th left relatively tothe axis of the main spindle without any strain being produced thereby or the driving impaired in any way.

7 Each tenon remains permanently in contact of the correspondinggroove, and its cylin-n driral port-ion engaging with the fly wheel, enables it to turn at an angle in its recess to the necessary extent in accordance with the degree of inclination of the driven spinrelatively to the main shaft.' In that way, a means for centering and driving the clutch cup of any clutchis obtained, the elements of said means forming a perfect universal joint.

. in the construction shown in the drawing,

it will be seen that the driving fly wheel 1 constantly drives the clutch cup 3 which is loose on the secondary or driven spindle 12 by means of the tenons A drain 13 Se cared to the spindle 12 by means of bolts 14, is arranged in the cup 3 and earriesa certain number of friction disks 15. alternately pl end with other simiiar'disks 16 supported by the cup A clutch collar 17 c0ntrolled by a. spring 19, brings the disks into tact and thus produces the couplin A d l er enables the spring 19 to be pushed nae. in order to throw out the clutch.

The devic can be modified indifferent constructive r. ys, for instance a fly wheel could be provided with a cylindrical recess for receiving the cup 3, instead of the spherical recess mentioned before. The centering is obtained in the same conditions, and the cup can be easily withdrawn or put in place. I i v The invention is applicable not only to motor vehicles, but also to any cases of transmission by clutch between two shafts, which while being normally connected in line, must he allowed freely to. oscillate relatively to each other.

Having now particularly described and ascertained the nature of my said invent-ion,

at its flattened portion with the bases;
